Built to ATA specs, the flight-style SKB 6-Space Rack Case is designed to hold rack gear securely, protecting it from the rigors of the road. High-impact plastic case locks tight with recessed hardware, and is lightweight but solid (similar SKB cases are used by the military for carrying small rockets!). Built-in rack rails have threaded inserts that can be replaced if they're ever stripped. First-class quality throughout! SKB is our premier supplier of instrument and gear cases. SKB builds their products with military-spec, ultrahigh molecular weight polyethylene and premium hardware. All SKB hardshell cases are unconditionally guaranteed forever. That means if you break it, SKB will repair or replace your rack case at no cost to you.
